摘　　要：受线损和设备运行状态的影响,线路的运行性能偏低,为此,提出35 kV及以上分线同期线损管理与采集运维消缺研究。构建35 kV及以上分线同期线损数据的影响因素序列曲线,并根据实际线损数据状态调整对应的状态因素参数,分别从电力线路、三相平衡、用电负荷状态角度入手,实现对采集运维的消缺处理。结果表明,设计方法下的线损电量下降了80 MW,对应的功率因数达到了0.95,且线损率仅为20%,电压不平衡度下降了3%。Due to the influence of line loss and equipment operation status,the operational performance of the line is low.Therefore,a study on the management,collection,operation and maintenance of synchronous line loss for 35 kV and above branch lines is proposed.Construct a sequence curve of influencing factors for synchronous line loss data of 35 kV and above branch lines,and adjust the corresponding state factor parameters based on the actual line loss data status.Starting from the perspectives of power lines,three-phase balance,and power load status,achieve defect elimination processing for data collection and operation.The results showed that the line loss power under the design method decreased by 80 MW,corresponding to a power factor of 0.95,and the line loss rate was only 20%,with a 3%reduction in voltage imbalance.
